Question about differences between cvs-1.12.13 and cvs-1.11.23

[Denis Migounov]

Hi all,

I'm working on integrating cvs-1.11.23 into OpenSolaris, and at the
stage of checking
interfaces I've found some differences between versions 1.12.13 and
1.11.23. Could someone please tell me
whether the following is true or not:

ENVIRONMENT VARIABLES:
--------------------------------------------------
CVSREADONLYFS, CVS_PROXYPORT, CVS_LOCAL_BRANCH_NUM, CVS_PID - all of
these are present in 1.12.13, but NOT in 1.11.23
CVS_SSH - is present in 1.11.23, but NOT in 1.12.13

COMMANDS:
-----------------------
ls, rls - are present in 1.12.13, but NOT in 1.11.23
(Note: I see "rls" mentioned here
http://cvs.savannah.gnu.org/viewvc/ccvs/NEWS?view=markup&root=cvs&revision=1.116.2.152
in the "Changes from 1.11.17 to 1.11.18" section, but there's no
description of the command in the 1.11.23 manual, also trying to run
'cvs rls' gives me the "Unknown command: `rls'" warning.)

Any help is appreciated.
